16. Security of Time Synchronization for PMU-based Power System State Estimation: Vulnerabilities and Countermeasures
Sammanfattning : Phasor Measurement Units (PMUs) constitute an emerging technology that is essential for various smart grid applications such as phase angle monitoring, power oscillation damping, fault localization, and linear state estimation. To obtain precise PMU measurements of voltage and current phasors, time synchronization in the order of 1 microsecond is typically required. LÄS MER
17. Investigating Software-based Clock Synchronization for Industrial Networks
Sammanfattning : A rising level of industrialization and advances in Industry 4.0 have resulted in Industrial Internet of Things (IIoT) gaining immense significance in today’s industrial automation systems. IIoT promises to achieve improved productivity, reliability, and revenues by connecting time-constrained embedded systems to “the Internet”. LÄS MER
18. Synchrophasor Applications and their Vulnerability to Time Synchronization Impairment
Sammanfattning : Recent years have seen the significance of utilizing time-synchronized, high resolution measurements from phasor measurement units (PMUs) to develop and implement wide-area monitoring, protection and control (WAMPAC) systems. WAMPAC systems aim to provide holistic view of the power system and enable detection and control of certain power system phenomena to enhance reliability and integrity of the grid. LÄS MER
19. Synchronization and Communication Results in Safety-Critical Real-Time Systems
Sammanfattning : A growing number of industrial control applications employ computer control to provide enhanced functionality and reduced cost. Many of these applications are safety-critical and require fault-tolerant techniques to provide an adequate level of safety. LÄS MER
20. Towards model-based development of heavy truck synchronizers
Sammanfattning : Gear shifts are becoming more and more important as engines are adapted to low speed and high torque working conditions. Synchronizers are key components for successful gear shifts. To adapt the synchronizers to future engines and thus new working conditions, improved development tools are needed. LÄS MER
